HW Set \# 5 Chapter 3 Evaluating Properties Problem 1 [3.77 6th] A system consisting of 1-kg of H2O undergoes a power cycle consisting of the following processes: Process 1-2: Constant pressure heating at 10 bar from saturated vapor. Process 2-3: Constant volume cooling to P3=5bar,T3=160C. Process 3-4: Isothermal compression with Q34=815.8kJ. Process 4-1: Constant volume heating. Sketch the cycle on T-v and P-v diagrams. Neglecting kinetic and potential energy effects, determine the thermal efficiency. [Answer: =0.05(5%)]
